All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example 1
As shown in fig. 1-9, a multifunctional staircase for interior decoration comprises a panel 1, the panel 1 is a square wood board, the thickness is 3-4cm, the weight is light and the bearing capacity is good, four corners of the lower end surface of the panel 1 are fixed with bases 8 through bolts, the four bases 8 are positioned on the same circumference, the bases 8 are aluminum alloy pieces, the weight is light, the processing is convenient, the bases 8 are provided with openings 801 with downward triangular cross sections, the inner end wall of each opening 801 is vertically downward, the included angle between the inner end wall and the outer end wall of each opening 801 is 20 degrees, the symmetrical surface of each opening 801 passes through the center line of the panel, the upper end of each opening 801 is a cavity 802, the lower end of each base 8 is provided with a two-stage telescopic rod 2, each telescopic rod 2 comprises an outer tube 201, an inner rod 202 is arranged in the outer tube 201 in a penetrating manner, the inner rod 202 is in clearance, the wall thickness is 4mm, and interior pole 202 is also for aluminium alloy square tube, and wall thickness 3mm, and interior pole 202 upper end welded fastening has bulb 204, and bulb 204 installs in cavity 802, and interior pole 202 passes opening 801 downwardly extending, and interior pole 202 can be followed opening 801 and swung, and clearance fit prevents to rock between interior pole 202 and the opening 801 lateral wall.
Install the telescopic tube device between two adjacent outer tubes 201, the telescopic tube device includes that both ends articulate to the first telescopic tube 3 of outer tube upper end, the telescopic tube device still includes that both ends articulate to the second telescopic tube 4 of outer tube intermediate position, second telescopic tube 4 includes base tube 401, pole 402 all wears to be equipped with in base tube 401 both ends, because in the use, the telescopic tube device is used as the crossbeam of staircase, base tube 401 inner chamber cross-section is rectangle, and the cross-section both ends are arc, base tube 401 is made by stainless steel material, the surface processing has the decorative pattern, the wall thickness is 3mm, pole 402 and base tube 401 clearance fit, the position department corresponding to pole 402 on outer tube 201 opens vertical rectangular shape through-hole 203, rectangular shape through-hole 203 both sides welded fastening has the connecting plate 5 of directional pole, pole 402 end welded ascending kink 403, the contained angle between kink 403 and the pole 402 is 90-130 degrees, the embodiment is specifically 120 °, the hinge pin 6 is installed at the joint of the bent portion 403 and the rod 402 in a penetrating manner, two ends of the hinge pin 6 are installed on the connecting plate 5 in a penetrating manner, when the second telescopic tube 4 is stretched, the end of the bent portion 403 can penetrate through the elongated through hole 203 and extend into the inner cavity of the outer tube 201, and the outer end of the bent portion 403 is arc-shaped.
In this embodiment, the difference between the first telescopic tube 3 and the second telescopic tube 4 is that the outer end of the rod of the first telescopic tube 3 is not provided with a bending part, the outer tube 201 is not provided with a long strip-shaped through hole at the position corresponding to the first telescopic tube 3,
the cross section of the rod 402 is rectangular, the inner end of the rod is provided with a groove 404, the outer wall of the base pipe is provided with a stop pin 7 at a position corresponding to the groove, in the embodiment, the stop pin 7 is a bolt, the thread is arranged on the base pipe, and after the installation is finished, the inner end of the stop pin is positioned in the groove and does not contact with the bottom surface of the groove.
The principle of use of this embodiment is as follows:
when using as the desk, four telescopic links are vertical downwards, at this moment, interior pole and the laminating of inner end wall in the opening, pole and connecting plate collinear, the kink outside is flat mutually with the outer tube inner wall, and the telescopic link can not outwards be spur, and the stable form when guaranteeing to use during the removal, can all move through first telescopic tube and second telescopic tube, the convenient removal.
When using as the staircase, upwards pull up the desktop, remove to interior pole lower extreme to the kink upside, at this moment, outside pulling outer tube, because four outer tubes pass through the linkage of telescope tube device, four outer tubes are even outwards swung, compress tightly to backing pin and ditch inslot end wall, obtain the staircase that four directions can ascend a height, and the kink outer end passes rectangular shape through-hole and extends to the inner chamber of outer tube.
In addition, it is worth noting that in this embodiment, when being used as an escalator, an operator can stand on the panel, and the safety factor is high.
After long-time use, because wearing and tearing and deformation, when using as the staircase, interior pole can follow the outer tube and move down, and the kink can stop interior pole and continue to move down this moment, guarantees the staircase and normally uses, for preventing interior pole lower extreme warp, still is fixed with the short square pipe 205 of being made by stainless steel material at interior pole lower extreme, and short square pipe cross-section is the same with interior pole cross-sectional shape.
It should also be noted that the included angle between the inner end wall and the outer end wall of the opening is 20 degrees, when any telescopic sleeve device is damaged, the telescopic rod swings outwards until the inner rod is attached to the outer end wall of the opening, and then stops swinging, namely, the escalator cannot continuously topple over, and the safety effect is good.
After the escalator is used, the telescopic rods are pushed inwards until the inner rods are attached to the inner end wall of the opening, and the panel drives the inner rods to fall down to obtain a table state.
For guaranteeing safe in utilization, when changing into the staircase form by the desk form, promote the desktop to the kink upside earlier, outwards stimulate the telescopic link 2-3, push down the panel this moment, because the elasticity of the tolerance of processing and material itself, the panel can move down to contacting with the kink, at this moment, continue outwards to stimulate the telescopic link again and compress tightly to the backing pin and the interior end wall of slot, obtain the staircase form, the telescopic link can not shorten again this moment, improves factor of safety.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
